18. Position and Distribution of Maxillary Displaced Canine
• Two standard lines for the mesiodistal placement evaluation of the impacted canine. The
area in which the impacted canine appears distal to the lateral incisor and not overlapping
with the lateral incisor root is called sector I (a). Sector II (b) is the area in which the canine
crown and lateral incisor root appear overlapped and sector III (c) is the area in which the
canine crown appears to have passed through the lateral incisor.

19. Position and Distribution of Maxillary Displaced Canine
• The bicondylar line (Warford et al. , 2003), the standard line in evaluating the impacted
canine angulation, is created by joining the most superior point on both condyles.

23. Attachments for bonding during surgical exposure of the
impacted tooth
• An impacted mandibular second molar has 2 eyelets bonded at the time of its surgical
exposure. Why two? If you have enough tooth surface, place two – it is a form of
insurance!

24. Attachments for bonding during surgical exposure of the
impacted tooth
• Three hand-welded eyelets to show the pliable band material (soft stainless steel tape)
with mesh base. A twisted 0.012” stainless steel wire rides freely in the eyelet and is stiff
enough to withstand any form of traction mechanism.

26. Non-eruption of a developing mandibular first permanent
molar
• Age 7.1 years. Note congenital absence of a single permanent mandibular incisor and
bilaterally of second premolars and second permanent molars. The right mandibular first
molar is impacted and held down in the body of the mandible. Note the distally hooked root
apices close to the lower border of the mandible. It is known that unerupted teeth often
develop enlarged follicles, but is this the outcome of the non-eruption or is it its cause?

27. Non-eruption of a developing mandibular first permanent
molar
• ETIOLOGIC FACTOR
• The cause for the impaction was therefore assumed to be its enlarged follicle.
• It is known that unerupted teeth often develop enlarged follicles, but is this the outcome of
the non-eruption or is it its cause?
• We know that a typical dentigerous cyst, which is etiologically, anatomically and
histologically the logical extension of an enlarged follicle (only semantics and timing
differentiate between the two), will drive the encompassed tooth to back-up along its
former eruption path, because its intra-cystic hydrostatic pressure overwhelms the force of
eruption

29. Non-eruption of a developing mandibular first permanent molar
• - A maxillary fixed appliance using an intermaxillary elastic, to be changed by the patient on a
day-to-day basis.In similar fashion, vertical traction would cause over-eruption of the teeth of
that side, generating a cant in the occlusal plane. Specifically, however, the maxillary first molar
was unopposed due to the absence (impaction) of its antagonist and any change in its vertical
status (over-eruption) would reduce the degree to which the impacted tooth could be erupted.
• - A temporary anchorage device placed in the maxilla, against which the patient would apply an
intermaxillary elastic, to be changed on a day-to-day basis. Since this approach did not use
dental anchorage, harmful effect on adjacent or opposing teeth would be avoided.
